Analysis of Polymers Only Soluble at Elevated Temperatures

Viscotek’s (USA) Model 350 High Temperature GPC (HT-GPC) System is a revolutionary advanced detector system specifically designed for the characterisation of polyolefins, and other synthetic polymers that are soluble only at elevated temperatures. The Model 350 HTGPC system provides absolute molecular weight without extrapolation or correction, molecular size (Rg and Rh to less than 1 nm), and intrinsic viscosity, as well as information on branching, structure and aggregation in a single GPC/SEC experiment. The system may also be configured with an Infrared (IR) Detector for short-chain branching analysis or a UV/VIS detector for copolymer compositional analysis. Representing a breakthrough in high temperature technology, the new system includes a High Temperature Triple Detector Array (HT-TDA), an Automated sample preparation & delivery system, a pulseless isocratic Pump, Degasser and OmniSEC GPC software for complete system control, data acquisition and processing. Engineered in a modular format for flexibility and enhanced reliability, the Model 350 HT-GPC features a detector module (HT-TDA) that is easily removed from the high temperature environment for routine maintenance.
The Viscotek Model 350 HT-TDA combines low angle light scattering with viscometry and concentration for complete and comprehensive macromolecular characterisation. All detectors reside within a temperature-controlled oven compartment (30 -175ºC) which has space for four analytical GPC columns. The 350 HT-TDA also features an in-line, self-cleaning filter and can be configured with only an RI, an RI and viscometer, an RI and light scattering detector or as a full Triple Detector Array.
